METHOD FOR CAPPING MQ-TYPE SILICONE RESINS

摘要

An intermediate reaction product to speed the reaction for producing capped MQ resins is disclosed. The intermediate reaction product includes an MQ-type silicone resin; a halosilane capping agent; and a polar organic compound. Optionally, a condensation catalyst and a solvent may be added to prepare the intermediate reaction product. Also, a method for preparing a reaction product to speed the reaction for producing capped MQ resins is disclosed. The method comprises the steps of combining ingredients comprising: an MQ-type silicone resin; a halosilane capping agent; and a polar organic compound. Optionally, a condensation catalyst and a solvent may be added to prepare the reaction product.
